NFC Tags

I bought some NFC Tags, but I have a few problems with them. I would like to use them as toggles (WiFi etc.).
1. They only work when my phone is unlocked (even though I checked the respective options in the NFC menu)
2. I can't get an NFC Tag to switch between network modes (2G, 2G/3G etc.)
3. I can't get an NFC Tag to toggle bedside mode
4. I can't get an NFC Tag to toggle GPS

For all actions not covered by phone's app Smart Tags, the best strategy is to have an app that performs the action you want, and then to use NFC to start that app. Another way is to find set of actions which result with the same result, e.g. for bedside mode:http://forums.crackberry.com/new-bla...ssible-875641/
For other two I don't have an idea .
